WITH THE OTHER END Jacobus Gerardus van den Bel, Overveen,

. Netherlands Application March 10, 1933, Serial No. 660,324 In the Netherlands March 11, 1932 16 0laims. (01. 24-305) When tying up bags and similar packings a string is laid around the open end of the filled bag, the ends of which are permanently fastened together by means of a seal of lead or of tin.

The tying up of a bag in this manner requires alarge number of manipulations, to wit laying the string around the bag, tying the string, passing the string ends through the seal of lead or of tin, tying the string again and finally clamping the seal of lead or of tin by means of sealing pliers.

It has already been proposed, in order to simplify this series of manipulations, to use an auxiliary means, consisting of a cord, fixedly vfastened with its one end to a holder in which a scalable cord clamp, consisting of two co-operating rollers, is arranged for clamping the end of the cord between these rollers.

Such an auxiliary means, however, is owing to its construction too expensive to be applied for all purposes coming into consideration and besides it has the disadvantage that it has to be sealed separately and, even then it does not offer {a sufiicientguarantee against loosening by unauthorized persons.

The object of the invention is to obtain an improved auxiliary means of this, kind, in which the above objections are avoided and the subsequent sealing has become superfluous;

To this end, according to theinvention, the clamping member is provided with a tubular portion having at the'inside projections or barbs for only allowing the cord composed of intertwined threads to pass in one direction.

With reference to thedrawing the invention will be illustrated by the description of some embodiments of the clamping member.

Fig 1 is a perspective view of the first embodimentyof which Fig. 2 is a longitudinal section on a larger scale;

Fig. 3 is a cross-section according to the line III-IIIinFig. 2;

Fig. 4 is a perspective view of the second embodiment;

Fig. 5 is a section according to the line V-V in Fig. 4; while Figs. 6 and '7 disclose modified forms of the clamping device according to my invention.

Acording to the drawing the clamping member consists of a metal body 1, in which a tubular channel 2 is arranged, of which two opposing Walls are provided with teeth or barbs 3 directed to each other, stamped out of the wall material. The one end. of a cord 4, composed of interof the cord. Therefore the bag is definitely guarantee to the buyers of the bags or bales of intertwined threads. 7 threads may be a. fibre, or a metal, dependent on the purpose in view.

twined threads, is fixedly fastened to the clamping body 1. i

When tying up a bag the free end of the cord is passed through the tubular channel 2 of the clamping member, in the direction of the barbs 3, after it has been wound one or more times around the bag.

When projecting from. the other end of this channel, the end of the cord is caught and the clamping member is pushed over the cord, until '65 the said member lies tightly against the bag.

If the clamping member is released it cannot slip back over the cord, as the barbs 3 immediately catch between the intertwined threads closed and can only be opened again by cutting the cord.

Although, when using the clamping member, the cord can first be wound around the bag and subsequently passed through the tubular channel and tensioned, it is simpler to pass the cord first through the channel. In this manner a noose is formed, which can forthwith b'ethrown around the open bag end and subsequently pulled. a

' Since the bag, after the pulling of the noose,

. cannot possibly be opened without rendering the noose use1ess,the clamping member will atthe same time serve as a seal which serves as a that the contents of thesame are untouched.

Anothenembodiment of the clamping member is also possible. The clamping member according to Figs. '4 and, 5 is made of a single metal plate folded in such a Way that two channels are formed, the channel 5 serving for the permanent clamping of one, end of theflcord', while the channel 6 isprovided with barbs for the one way passingyof the other end of the cord.

It is however required that. the cord consists The materialof these It is furthermore possible-to clamp the cord permanently in the channel 5 not with one end, but at a point between the ends, one of the ends of the cord being provided with an eye, as in Fig. 6. Before passing the relative cord end through the channel 6, this end is first passed through the eye of the other end of the cord 105 and only then passed through the channel 6.

In this manner a loop is formed which, after the other end has been drawn through the channel 6, cannot be unfastened any longer and may serve for connecting together different objects,'110

e. g. the lugs of the door and the doorpost of a railway carriage for sealing said door.

Instead of providing one of the ends of the cord with an eye the cord may also be fixedly fastened in the channel 5 at a point between its two ends as well as with one of the said ends, as in Fig. '7, thus forming a double end of the cord from which a loop may be formed in a similar manner.

I claim:
